The pic of the evap temp sensor is up: http://www.jrcormier.com/prelude/jdm...l/dcp00693.jpg

I could sell you my extra one but you would get one faster is you went to the junkyard. Just let me know if you want it.

I dont have the male part of the evap sensor.....where do I connect it to? am i supposed to short out the thermostat since it has 3 wires?

but thats not VERY important to me right now, i have never had a working compressor since i bought the car

I actually need to know why my mode control motor quit working ever since I wired and re-installed my blower motor?
all the modes worked fine, now it doesnt move but all 4 fan speeds are awesome....any insight as to whats wrong? bad ground or something?

Can you take a picture of the thermostat? I'm not sure you're looking at the right thing...

There's not much change in the wiring for the mode control motor so it shouldn't just quit like that, maybe a connection that was loose or something...

I'll check tonight if I can find something to help you

94LOOD · 01-20-2004, 04:00 PM

the left is my USDM sensor and to the Right is the JDM one,
isnt it just the black covered wire/sensor that is in the evap. unit?

and about my mode controls, Im gonna go re-check the wiring....I keep the same USDM motor for the modes correct? cuz I was also sent a new motor but it WAS working 100% fine w/ the one already on the heater

Your A/C thermostat is nothing like mine, I thought you had the wrong part when you said you had 3 wires but I checked on slhondaparts.com to see what part it was and noticed that there are 2 different A/C thermostat, on the 92 it's the part #33 and on the 94 it's part #32 on these diagrams:

Anybody has a 94+ helm that could scan the wiring diagrams for that area? So we can find out what's this 3rd wire for.

As for the mode control motor, yes you can keep the USDM motor, that's what I did. I didn't have time to check in my Helm yesterday, I'll try to check tonight.

Well...as far as i remember in this very thread The blu/yel wire from the 20-pin, connects to one of the wires (blu/yel) that used to connect to the USDM thermostat (this wire runs to the A/C pressure switch in the car)

also I remember Caz telling me that all sensors except for the sunlight one are just resistors without polarity, so it won't matter which wire is ground or the other.

So just cut off the connector from the JDM evap. sensor and splice a wire to run to Pin #17 (ground, lt grn/red) in the 20-pin connector and the other to pin #9 (brown) also in the 20-pin connector.

I hope this takes care of your problem...Let me know if you need me to explain this better

94LOOD · 01-21-2004, 10:14 PM

thanks alot ill get that hooked up tonight,
as for my Mode control....forbidden dont waste your time, I figured it out earlier today and it works perfectly. thanks a lot though

tomarrow I'll hopefully finish the sensors and find a wire for the memory and I should be pretty much set!

Bertico78 · 01-22-2004, 02:56 PM

awesome....good luck man! looks like soon you'll be part of the JDM CC club!!

94LOOD · 01-25-2004, 09:57 PM

well i got the oustide temp sensor mounted and wired
found a memory wire and spliced it...
now i just gotta ask for pics of where to mount my interior temp sensor?

i see a few on the site but they are old and all i get is an X

on dude had a 92 and mounted it in his center console dummy button buuuut mine doesnt fit :-(

im so friggen close! i wanna finish this but BOO school and work, they take up too much time

Mine is mounted between the steering and the climate control unit like they are on JDM cars, though you have to make a hole in the dash so make sure you won't change your mind afterward.

You can see the hole in these pictures:

Bertico78 · 01-26-2004, 07:06 PM

you can make it fit in your "dummy buttons" in your console, just align it exactly in the middle of one and crazy glue it. That's where mine is.

94LOOD · 01-26-2004, 07:36 PM

do you think it still works correctly in that dummy spot?

oh and I think i need to find a new memory wire, it will remember the settings if i turn the car right back on....but if I leave and come back later then i still have to press the front defog button to turn everything on...... bummer haha

Bertico78 · 01-27-2004, 04:19 PM

yes it reads the temperature pretty good. it'll prob. think it's colder if you place a cold drink in your cupholder though...lol

94LOOD · 01-27-2004, 07:47 PM

yea well its all in and i can only assume its working correctly...dont really know the best way to test it or nothin...

but using the stock harness for the CD player/ HU....what would be the best wire to tap into for memory?

Bertico78 · 01-27-2004, 08:27 PM

the white/yellow one for memory.

To make sure the sensor works I just watched how the air mix motor behaved under different temperatures.
Like in early morning being cold, just raising the temp a couple of degrees should make it move progressively as to opening the heater doors..
In a hot afternoon, it won't even move the doors until you set the unit for full hot -32 degrees.

94LOOD · 01-27-2004, 09:59 PM

the wht/yel one on the JDM unit is the memory, but is it the same for the stock headunit? cuz i just tapped into that harness' wht/yel wire and it did the exact same thing as the cig. lighter wire that i had it tapped into before.....
it will keep the settings for like 1 min. then after that it goes to the 25 like it always starts off at......

grrrr why is memory giving me sucha hard time??
ps. is there any reason why some parts of the display should be appearing / disapearing whenever i press other buttons?

for instance sometimes when i press a button, my blower controls just vanishes.... will memory hopefully solve that?

It looks like the memory wire isn't connected because even without the memory wire mine would keep it settings for a few minutes
after I turn the car off. Maybe check to make sure you don't have a bent or broken pin on your unit.

The only time stuff disappear on my unit is when I press auto or off, on auto only the temperature is on the display.

94LOOD · 01-28-2004, 09:00 PM

it seems like if there were a memory connected, then i would be having the display disappearing....

95VTEX · 04-14-2004, 01:59 AM

can anyone do a write up on how to make your own power transistor. I can't find one and I have heard I can just make one with simple radio shack stuff. or if anyone had a spare I would rather get the real thing. thanks
